@darb0505 , thank you very much for your response. Regarding entering the command to change the hostname, I would also need to change the username and password used to connect which have also changed. Can that be done on the same command line?
Also, what are the risks of making this change? Is there a potential for causing an outage of the OnTAP Select VMs?
Lastly, you said "I would also verify that the plugin is fully installed and working on the new vCenter". I was unaware that OnTAP Deploy installs as a plug-in in vCenter. If so, that definitely didn't happen when we set up the new vCenter. Client Plug-Ins show the other NetApp plug-ins like VSC and SnapCenter, but not OnTAP Select. What would I need to do to correct this?
